The pigment_pattern works, at least, because it isn't applying a texture within
a texture. The pigment_pattern creates a grayscale pattern (it will convert
normally colored patterns to grays) that the texture map. It's not trying to
undo turbulence, the turbulence isn't applied to the underlying pattern to begin
